Lloyd's Book of House Flags and Funnels 1912 shows the house flag of "Bremen-Vegesacker Fischerei Gesellschaft" (#14, p. 37), a company based in Grohn, as white with a vertical border along the hoist made of two columns of six squares, alternating red and white, two horizontal stripes on top and bottom of the flag (width, one square), and the black letters "BV" in the middle.

The name of the company reads "Fishing Company of Bremen-Vegesack". Vegesack is a borough of the town of Bremen, while Grohn is a borough of Vegesack.
Founded in 1897, the company became one of the biggest herring fishing company in Europe. In 1895, the company purchased the steel saillogger "Vegesack BV2", used as a herring fishing vessel (drifter) at the North Sea. Sold in 1921, the ship had several successive owners, and is still operate by the "Maritime Tradition Vegesack Nautilus" association, as the oldest Europen herring drifter.

Erste Deutsche Walfang Gesellschaft

image by Klaus-Michael Schneider, 9 Oct 2009

Though it is known, that the company "Deutsche Walfang AG" was located in Wesermünde, no one knows exactly, when it was established. Some say, it was established in 1912 as "Deutsche Walfang-Gesellschaft Sturmvogel", which was located in Lüderitzbucht, then in German South West Africa, the nowadays Namibia.
In 1935 Henkel & Cie OHG, located in Düsseldorf, overtook the shares of the company from the cities of Bremerhaven and Wesermünde. The company was renamed into "Erste Deutsche Walfang-Gesellchaft(1st German Whaling Society/EDWG). The freighter "WÜRTTEMBERG" was modified by Blohm & Voss dockyard and renamed as "JAN WELLEM" in 1936. The vessel took part in whaling in the South Pole seas together with eight other company vessels between 1936 and 1939.
After WW2 all ships got lost and the company was not restarted. The know-how was given to Aristoteles Onassis, who had no experience in whaling. But he too gave up in 1954.
EDWG was kept however as ship-management company for the vessels of Globus-Reederei and Meridian Reederei, which had been established by Henkel in 1951. In 1956 EDWG was dissolved and completely overtaken by Globus-Reederei.Source: Klaus-Peter Bühne's webpage , translated by Klaus-Michael Schneider, 9 Oct 2009
